Title: Electronic motor speed control
IPC: H02P7/288
Filed: 1966-09-23
Abstract: 1,144,937. Automatic speed control. LEAR JET INDUSTRIES Inc. Sept. 23, 1966 [Sept. 27, 1965], No.42657/66. Heading G3R. [Also in Division H2] For speed regulation, the armature 17 of a D.C. motor is arranged in a four-arm bridge circuit comprising earth-connected resistor 32 and divided resistor 40, the voltage across terminals a, b representing the back e.m.f. and speed of the motor. The system is damped by adjusting wiper 41 to provide a small voltage across terminals a, b, when the motor is stalled, potentiometer 38 being adjusted to set the required speed. Initially, transistors 50, 63 are non-conductive so that power transistor 31 is fully conductive to accelerate the motor. As the back e.m.f. increases, the transistor control-chain 50, 63, 31, is activated to reduce the motor current until the speed approaches the requisite value. Temperature changes of the transistor 50 are compensated by a resistor 55 having a positive temperature coefficient. Alternatively, shunt resistor 56 may be replaced by a thermistor. The control system is insensitive to a wide range of battery voltage applied to the terminals 27, 28. In a modification, an additional stage of control amplification is provided by a transistor between the transistors 63, 31. A diode across the output terminals of the bridge prevents damage to the transistor 50 by reverse voltage. Dynamo electric machines. Armature resistance variations are reduced by mounting brushes 86 on spring-biased metallic strips 88 to increase the pressure against the commutator, the brushes being made of low resistance material such as a metal-graphite composition.

Title: Altimeter range computer
IPC: G01S13/70
Filed: 1970-09-10
Abstract: 1311337 Altimeter MESSERSCHMITT-BOLKOW-BLOHM GmbH 10 Sept 1970 [14 Oct 1969] 43362/70 Heading H4D In an altimeter emitting pulses of radiation, preferably laser light radiation, and having an automatic tracking gate facility, loss of the echo in the tracking circuit causes a change over to a search mode and the movement of the range gate, initially through a range in the vicinity of the range of the echo when lost and then, if acquisition is not obtained, through the whole range of the altimeter. Production of the range gate is by standard comparison in gate generator 3 of a sawtooth voltage from generator 2 starting synchronously with each transmitted pulse, and a voltage from generator 4 representative of the tracked range, the tracking loop being completed by the output of gate error amplifier 6 controlling generator 4. If the echo is lost a search generator 9, Fig. 2, causes the range voltage generator 4 to produce a slow sawtooth varying by a small amount about the voltage representative of the lost range. If the echo is not reacquired the generator 4 is caused to produce a slow sawtooth extending over the full range voltage. In the tracking mode with switches 51 and 52 as shown, the range representative voltage is fed in at 110 and is stored across capacitor 35. Loss of the echo causes switch 52 to move to its centre-" no input "-position and a sawtooth generator 12, 13, 21, 31 to produce a sawtooth at the input of transistor 14. Conduction of transistor 14 at predetermined level of the sawtooth causes a pulse which via inverter NAND element 41, transistor 15, Schmitt trigger 43, 44 and NAND gate 43, causes the enabling of transistor 11 and the cessation of the sawtooth. The sawtooth output 100 thus varies about a voltage proportional to the voltage across capacitor 35. If the echo is not thus reacquired the switches 52 and 51 are set to their lower positions such that the full range voltage on input 54 is applied across the capacitor.

Abstract: 1,237,822. Food product. H. A. HOFFMAN. 10 Sept., 1969, No. 44621/69. Heading A2B.  A method of forming a food product comprises the steps of impregnating substantially solidly compacted fibre-like chunks of a material derived from a solvent-extracted meal of proteinaceous oleaginous seeds, for example soybeans, with an edible oleaginous material, for example coconut oil, so as to effect absorption substantially throughout the chunks whilst substantially retaining their initial shape and hardness, and heating the impregnated chunks in water, which may contain hydrolysed vegetable protein, caramelized sugar, and salt, for sufficient time to soften the chunks to chewable consistency, the chunks having the general shape of the unimpregnated chunks but having an increased volume. The initial chunks may be prepared by subjecting the moisture-containing solvent-extracted meal to elevated temperature and pressure for sufficient time to convert the moisture to steam whereby the meal is debittered and is compacted into a hard substantially fused mass of generally fibre-like material, which is then fragmented into chunks.
